Best travel eSIM for Asia

The best travel eSIM for Asia depends on which countries you visit, how long you travel, and whether you need unlimited data, hotspot, or business reliability. Simscanner compares regional eSIM brands across Asian countries, then links to country-level rankings where coverage and speed can differ. A named winner only appears once Asia data is verified.

A regional Asia plan covers a defined set of countries under one purchase, so for many trips a single eSIM is enough. The exact list varies by brand , Simscanner publishes the member-country list per plan. Some plans exclude one or two countries inside the region, so always check the country list before relying on coverage.

Not always. A regional eSIM rides on different local networks in different countries, and brands set their own member-country lists. A brand can perform well in Japan and weaker in Thailand. Simscanner checks country-level networks where data is available and links to per-country pages for the detail.

Most do, with a fair use cap. Holafly, Airalo, Nomad, Saily and Jetpac all sell an unlimited or daily-capped Asia tier; Ubigi is fixed-data only. Holafly's is unlimited with a roughly 90 GB monthly high-speed window, while the others cap high speed per day (Saily 5 GB, Airalo 3 GB, Jetpac 3 GB, Nomad 2 GB) before slowing. The unlimited and FUP table on this page lists the sourced allowance and throttle for each brand.

FUP means fair use policy. It is the limit after which a brand may reduce the speed of an unlimited plan. The high-speed allowance varies by brand: Holafly's Asia eSIM gives roughly 90 GB per month before throttling to 256-1024 kbps, while daily-capped plans differ - Saily allows 5 GB/day before slowing to 1 kbps, Airalo 3 GB/day before 1 Mbps, and Nomad 2 GB/day before 1000 kbps. The unlimited and FUP table on this page lists the sourced allowance, throttle and hotspot rule per brand.

Usually, yes, but the rule varies by brand. On the sourced Asia plans, Airalo, Nomad and Saily allow tethering, Ubigi permits data sharing, and Holafly lets you share roughly 1 GB per day. Some brands restrict hotspot on unlimited tiers, so check the hotspot column in the unlimited and FUP table on this page before relying on it.

A regional eSIM is convenient, but performance still varies by country and by the local network the eSIM connects to. Coverage, speed, and reliability can differ between, for example, a major city and a rural region. Country pages carry the full per-country ranking, so they remain the most precise source even when a regional plan is the practical choice.

No. Region rankings come only from sourced data measured against published methodology. No brand pays for ranking position, inclusion, language, or visibility. Editorial decisions are independent of any commercial relationship. The full policy lives at the zero paid placements page.
